"WILLIAM H. GRUBB, OF QUINOY,ILLINOIS, ASSIGNQR OF ONE-HALF TO J.

M. LIONBERGER, OF SAME PLACE.

ADJUSTABLE HINGED WINDOW OR DOOR SCREEN.

SPECIFICATION forming part of Letters Patent No. 441,096, dated November18, 1890.

Application filed July 18, 1890. Serial No. 359,170. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM H. GRUBB, a citizen of the United States,and a resident of Quincy, in the county of Adams and State of Illinois,have in vented certain new and useful Improvements in Adjustable HingedWindow and Door Screens; and I do declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to lettersof reference marked thereon, which form a part of this specification.

Figure 1 of the drawings is a perspective inside view of the window andscreen. Fig. 2 is a horizontal section, and Fig. 3 is a detail view ofthe latch.

This invention relates to certain improvements in window-screens, havingfor its object to effect the ready putting in place and removal of thescreen; and it consists in the construction and combination of parts ashereinafter disclosed.

In the drawings, Arefers to the screen, the frame a of which is made insections A A hinged together, as at b.

B is a spring-metal plate or latch pivoted at one end to theframe-section A on the side opposite that to which the hinges areattached, the frame thus being adapted to be fixed against the action ofsaid spring, the purpose of which will appear farther on.

The plate or latch B is provided in one end portion with anapproximately L-shaped slot 0, engaging a headed stud or screw cl,projecting from the frame-section A; also, at the same end the latch isprovided with an operating finger-piece or stud e.

' It will be seen that in order to put the screen in place in the windowit is only necessary to move the latch so as to disengage the short armof the slot from the stud d and to flex or bow the frame with itsattached wire-cloth, thus bringing it within the limits of the openingof the window-frame and permitting its insertion therein. The spring orrecoil of the metal of the latch thus flexed with the flexing or bowingof the screen will have the effect to automatically restore thelatter toits original or normal position. Now, by reversing the movement of thelatch the short arm ofv its slot will again engage the stud d and lockthe screen-frame sections in position, preventing their deflection andconsequently the removal of the screen from the outside.

In like manner, as in manipulating the screen for insertion into theWindow-frame, the screen is adapted to be removed therefrom.

Having described this invention, what I claim, and desire to secure byLetters Pat'- ent, IS-1" The window-screen having its frame made ofhinged-together sections and the springmetal latch or plate connected toone framesection and having an approximately L- shaped slot engaging astud on the other frame-section, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
